In virgin XCP 0.1.1 (right from the install iso), a working CentOS/RHEL 5.4 VM cannot be created, despite there being a template for it. The VM can be created without error but attempting to start it results in a “no output from bootloader” message”

The cause of this is a missing file in the 0.1.1 distribution. Download this file:

I noticed that my past two guests (Oracle VM and Windows 7 VM) were both unable to connect to the Internet once I had them installed. Here are the steps I took to correct the problem on OpenXenCenter and get Internet connectivity working on my XCP guests.

1) For your specific VM – select the Network Tab

2) Click the Add Interface button

3) A new Window appears – New Virtual Interface Network
a) Pull down the arrow on the Network: Location item and select Network 0
b) MAC Address – I left this on Auto-generate
c) Limit – I left this blank
d) Select OK

4) Shutdown and Restart your VM and the Network Tab will now show you a MAC address with the Active column set to TRUE

That was all it took to setup a Network Interface from the Guest to the Domain0 Guest.

Welcome to the new Xen.org weekly newsletter with a variety of information to keep you updated on all things Xen. This newsletter is an upgrade from my previous weekly communications and is meant to offer a broader scope of Xen.org activities. Please feel free to contact me with suggestions for the newsletter.

Xen Directions South America – In conjunction with a soon to be announced Linux Foundation event in Sao Paulo, Brazil on August 31 – September 1.

Xen Directions North America – In conjunction with LinuxCon 2010 in Boston, MA we will hold a day long event on August 9 with the full LinuxCon event on the 10-12th.

I will be adding more information on these two events on the Xen.org events page. Please remember that Xen Directions are more marketing focused than our developer oriented Xen Summits. If you are interested in participating as a speaker at either of these events please contact me.

Finally, thanks to Marco Sinhoreli in Brazil for his outstanding efforts in helping to create our first Xen.org event in South America.
